The meaning of CIS-TRANS ISOMERISM is geometric isomerism in unsaturated compounds or cyclic compounds depending usually on the presence in the molecule of a pair of substituted groups (as unsymmetrically substituted methylene groups) so that the isomers
Cis-Trans Isomers Exhibit a Type of Stereoisomerism Where the Atoms Have Different Spatial Arrangements in 3-D Space. Learn about Cis-Trans Isomers with Examples.
Heat induced synthesis of linolenic acid isomers-a reference standard It may be concluded that ppiases catalyze the peptidyl-prolyl cis-trans isomerization, the ratelimiting step of protein folding, which is essential for newly synthesized protein to get its correct functional form. The cloning and...
2. Definition of Cis and Trans Isomers: - In cis isomers, similar groups are on the same side of the double bond or ring, while in trans isomers, similar groups are on opposite sides. This spatial arrangement leads to different physical and chemical properties. 3. Role of Pi Bonds: - ...

Re:Cis/Trans Isomers « Reply #1 on: September 14, 2004, 12:27:44 AM » Cis and trans are actually rather imprecise ways of naming compounds and lead to a lot of confusion. Unfortunately it's part of the chemistry vernacular.Your first example doesn't make sense because it isn't...
The cis, trans isomers of the conjugated trienes present a difficult problem for complete determination of structure.Several methods of attack have been outlined, and application of two of them have been made to α and β eleostearic acids, α and β licanic acids, and to pseudoeleostearic ...
